    When I put my 1.8T through it's MOT early this year, it just about passed the emissions and the tester had to run the engine for a good 10 minutes before the emissions where low enough for it to scrape through. I also checked the MOT history on the car and it's failed the last few MOT's on emissions, but passed the retest (Somehow)!

    So the cat & manifold was replaced today. I managed to get a new cat genuine cat from ebay for just over £100 and I got a manifold for £15. One thing to note was the manifold was from a B6 1.8T & the cat had a part number which indicates it was only for a quattro version of the 1.8T. However both fitted perfectly without any modifications required.

    When I ripped off the old cat I found a completely empty cat, the dam thing had been through a decat, so if anyone want a free decat, cat! then then send me a PM, the only cost would be the postage. However you may find it difficult to pass the emission tests in the future.:banghead:

    I had already replaced the downpipe, got one from a VW dealers in Leeds, as the flexi section had almost completely failed. Would be interested to see how long aftermarket system lasts as you can easy get over 100K miles & 12 years from an OEM system.

    My cat was the same lol.

    I suspect when they get old they get blocked up, and someone just whips them off and knocks the guts out as a "get me by" quick fix.

    The bolts on mine suggested it had been on there like that for a LONG time, yet had "passed" numerous MOT's perfectly fine.

    Finished the job off this morning, and the whistling noise & exhaust blowing noise have gone, so I've now got a nice quiet motor as the whistling noise was driving me mad....

    I think the my cat had been gutted about 4 years ago as that was when I noticed the emissions were first listed as a failure on the MOT history web site.

    Go on then... I'll take it off your hands.

    Let me know how much the postage will be.

    Cheers,
